Now the brave new world might see SAR differently and insist that it is conducted within stricter civilian rules and regs - if that is the way it must be then so be it but if it compromises the quality of SAR service and UK cover then not much will have been achieved by the contractorisation will it?
..and the only way you are going to be able to quantify that last sentence is by the number of lives not saved, searches not conducted or transfers not carried out, that you can prove would have been carried out, under the MilSar system.
Oh, and I suppose you can chuck in some cost calculation for good measure!
